Some of what is said here is not actually accurate and should be updated, perhaps when a new Fedora CLA is drafted or when Fedora documentation switches over to CC-BY-SA. I note the following items:
1) It is not necessarily correct that "At this time, all license agreements shown are governed by the contractual laws of the State of North Carolina and the intellectual property laws of the United States of America, unless otherwise indicated", unless there is an actual choice of law clause stating as much. (It may of course be correct by operation of law.)
2) The Fedora CLA has never been a mechanism for "establish[ing] copyright control under Red Hat, Inc. on behalf of the Fedora Project" -- at least not the way I understand "copyright control". The Fedora CLA, in its current form, is a license from the contributor to Red Hat; the contributor retains copyright, as in any other copyright licensing arrangement. Therefore, it is not true that the CLA causes "a single entity [to] hold copyright". Future revisions of the Fedora CLA will make this very clear.
